I think we should fight greenhouse emissions as much as possible, but at the same time we should be realistic and plan accordingly. We should have a disaster plan (how to we move everybody to cities that won't be flooded, any nuclear plants on the coast to take care of? etc.) and a geo-engineering plan (can we capture this CO2 in some way?) and... a space exploration plan. who knows? maybe defeating aging will push us to think longer term

> a space exploration plan As you talk about a dramatic disaster touching billions of people, would you mind to explain me how space exploration could make a dent in such a colossal situation?

  Ah, that's easy. The best sites to test designs for sustainable colonies on Mars are in the deserts; the best sites to test designs for sustainable colonies on Europa are in the oceans; the best sites to test designs for sustainable colonies on asteroids are at the tops of mountains. Once you have sustainable colonies in the deserts, the oceans and the mountaintops, you have much less urgency to move them out to space...

  If you put yourself on a very long term trajectory, say 500 years, don't you think the only way to make a dent on the situation is space? I mean, what else would you do as a species? How else would you make sure humanity has a bright future?

I moved to a (cold) place 5500 ft above sea level nearly 20 years ago partly with global warming in mind. Unfortunately I didn't anticipate that climate change would lead to a significant increase in wild fires too.

The worst care scenario for global warming is lightyears better than living on Mars, etc.

  It's not if you take future into account. Mars and space exploration have a future, Earth who knows? At this point staying on 1 planet it's a bit of a gamble
